Design of Experiments Applied in Injection Molding

This Report has been authored by:R.J. Del Vecchio at Technical Consulting Services

Powerful interactions affect the performance of many rubber and plastics processes. Unfortunately, these critical effects cannot be revealed by the traditional scientific method, which dictates changing one factor at a time (OFAT). This case study provides inspiration to overcome the limitations of OFAT via a very simple design of experiment (DOE) called a two-level factorial.1 By employing a multifactor approach, the technical staff at a custom rubber molder uncovered a combination of material selection and manufacturing protocol that created unacceptable results. Armed with this process knowledge, they achieved a breakthrough in quality improvements.
